Description

TECHNICAL FIELD[0001]The present invention relates, in general, to rotary engines and, more particularly, to a rotary engine which prevents the loss of kinetic energy occurring in engines using reciprocating pistons or propellers, thus maximizing the thermal efficiency of the engine.BACKGROUND ART[0002]Conventional reciprocating piston engines, in which compression, combustion and expansion strokes are conducted in a single cylinder, are disadvantageous in that excessive kinetic energy loss is incurred by reciprocating motion of the piston, high-speed rotation is difficult, and output power is low compared to the size of the engine. Gas turbine engines and wankel engines, which are kinds of rotary engines, are representative examples of engines which were developed to overcome the disadvantages of the reciprocating piston engines. Typically, the conventional gas turbine engines consist of three parts: a compressor, a combustion chamber, and a turbine, and have a structure in which, ...

Benefits of technology

[0017]In a rotary engine of the present invention, complete combustion of fuel is realized, and explosive combustion power is transmitted to an output shaft without power loss, thus maximizing the efficiency of the engine. As well, the rotary engine of the present invention makes it possible to minimize vibration, noise and pressure leakage. Furthermore, because complete combustion is realized, there is an advantage in that automobile exhaust fumes, which are principal factors of air pollution, are minimized.

Problems solved by technology

Conventional reciprocating piston engines, in which compression, combustion and expansion strokes are conducted in a single cylinder, are disadvantageous in that excessive kinetic energy loss is incurred by reciprocating motion of the piston, high-speed rotation is difficult, and output power is low compared to the size of the engine.

However, the gas turbine engine has a structure in which output power is generated by high-speed current striking the turbine, but the pressure of combustion gas is not directly converted into output power.

Therefore, the gas turbine engine has a disadvantage of having low thermal efficiency.

However, there are disadvantages in that the structure thereof makes complete combustion impossible, and a fuel consumption ratio is very low due to high heat loss.
